Driver air -conditioning training device

Ship --r -conditioning tr--ning assessment device is based on the "Standards for the Education Industry of the People's Republic of China (Equipment and Equipment Equipment Equipment for Refrigeration and *r Conditioning and M--ntenance in Instrument and Equipment)," The skills requirements of actual production and occupational positions are developed and developed in accordance with the teaching, tr--ning, and experimental requirements of vocational and undergraduate colleges. This device is suitable for the installation and m--ntenance and m--ntenance of mechanical and electrical equipment in higher vocational colleges, secondary vocational schools and undergraduate colleges, the application and control of electromechanical technology, electrical operation and control, electrical technology application, motor and electrical appliances, refrigeration and --r conditioning equipment use and m--ntenance. "Refrigeration and *r Conditioning Machine Equipment", "Installation and M--ntenance of Refrigeration and *r Conditioning Device", "Refrigeration and *r Conditioning Automation and Mechanical and Electrical Integration", "*r Regulatory Technology and Application" and other courses. This device is also suitable for the appr--sal and evaluation of intermediate, ** workers and technicians of related majors and the design and development of central --r -conditioning topics.

Two and characteristic

1. Full physical tr--ning tr--ning This device is to minimize the ship's --r -conditioning, while ensuring the integrity and rationality of the entire central --r -conditioning system. The entire tr--ning equipment can demonstrate the summer refrigeration cycle and winter heating cycle Instruments, cooling towers, and simulation boilers are equipped with temperature measurement points, which is convenient for students to observe and understand the changes in various parameters and the working conditions of the system. And add some auxiliary configuration to allow students to fully grasp the central --r -conditioning skills knowledge

2. The ship's --r -conditioning tr--ning device has electric power drag control, automatic control. Mold control method, with temperature sensor and collecting instrument.

3. Strong intuitiveness: The ship --r -conditioning device adopts an open design, and the control circuit and the refrigeration pipeline system are directly displayed. The device stickers have the name logo. Students can intuitively understand various devices.

4. Strong tr--ning: The actual circuit can control the entire process of tr--ning refrigeration systems and systems of electrical industry automation system.

5. The device has a manual expansion valve, which can work in the heating expansion valve when the automatic thermal expansion valve is damaged.

6. The fault alarm system, when the device f--ls, the fault alarm system will automatically ring.

7. The host compressor is equipped with a refrigeration energy regulating valve device, which can protect the refrigerant flow supply of the compressor in a single cold storage.

The m--n purpose:

This experiment should realize the work process that can realize hybrid heat exchange equipment. The data measured by the experimental table enable students to master the working method of hybrid hot -quality exchange and can analyze the factors that affect their thermal exchange effects.
